Smart Parking Metersh1kari
Security through obscurity is unfortunately much more common than people think: many interfaces are built on the premise that since they are a "closed system" they can ignore standard security practices. This paper will demonstrate how parking meter smart cards implement their protocol and will point out some weaknesses in their design that open the doors to the system. It will also present schematics and code that you can use to perform these basic techniques for auditing almost any type of blackblox secure memory card.
